Installation for heating, ventilation or air-conditioning of a long- distance bus

摘要

Described is an installation (10) for heating, ventilation or air- conditioning of a long-distance bus, which in a transverse direction in a housing (12) has a heat exchanger and, for passing air through the heat exchanger (14), radial-flow blowers (28, 30, 32) which are arranged one above the other and disposed in displaced relationship one behind the other. Downstream of the heat exchanger (14) the housing (12) has a collecting chamber (20) which is in fluid communication with longitudinal ducts (36) by way of two lateral corner regions (22). The radial-flow blowers are in the form of suction blowers (28, 30, 32) which are disposed in the corner regions (22) in two groups which are spatially separated from each other. The suction blowers (28, 30, 32) are arranged on partitioning walls (24) which are provided with openings (26) therethrough and which extend over the corner regions (22) between the housing (12) and heat exchanger (14) and which separate the collecting chamber (20) from the corresponding longitudinal duct (36). The suction blowers (28, 30, 32) are inclined at acute angles (&agr;, &bgr;) relative to the horizontal and relative to the longitudinal direction.
